Series 3 Gtr Gearbox

[Buraz]

Hi guys, iv got a brand new series 3 box installed not long ago. It's been bedded in properly and hasn't been mistreated at all. Just street driving, did a few launches in it but that's it. Car is making 360rwkw atm.

Now just today iv noticed 1st gear on de acceleration sounds like a straight cut gear. It's not too loud at all but has bit of a whine to it. This occurs on very low speeds like 30kmh or so de accelerating and when clutch is depressed still whines a little. Pull it out off 1st while still rolling and the noise is gone. All other gears are perfect and shifts perfectly too.

I haven't noticed this before, maybe it was always like this and normal maybe not. Is this something normal or has something gone wrong??

Thanks in advance

My ser 3 does the same, I'm thinking it was front diff?

I don't think it's the diff, otherwise it'd do it in other gears too. Iv read this exact whine is normal on Evo's and iv seen it on YouTube it's identical to mine. They all reckon it's normal and develops this noise after a few launches.

Only thing is I can't remember if it was always here and I just didn't notice it

Can anyone else shed some light on this? Surely it's not just us two who have noticed this

i have the same issue and would like to know if front diff is the culprit

btw: i have done both diff oils 30k ago but dont recall if issue was present prior to the change, running shockproof

Was there a solution here? I also have a new s3 transmission and it sounds like the same.
